It isn't a problem with Messenger Plus! afaik, I'm pretty sure that it's a problem with MSN Messenger itself, there is a lot of things like this occuring at the moment...
I heard that if you rename the msn messenger folder, then the problems no longer occur, but that's only what I heard, nothing else, give it a try...
I'm sure that the bug will be fixed in the latter versions of MSN Messenger...
